Step 1. Calculate Charlson comorbidity score
Indicate "yes" for the comorbidities that the patient has. This validated algorithm (Charlson, ME et al. J Chron Dis 1987; 40(5):373-83.) assigns a point value to the various diseases. The patient's raw score will then be reassigned into the collapsed Charlson score groups for use in the risk score calculation. Group 1 is a score of zero, Group 2 is a score of 1, Group 3 is a score of 2, and Group 4 is a score of 3 or higher.  

Comorbidity

AIDS  
Cerebrovascular Disease  
Chronic Pulmonary Disease  
Congestive Heart Failure  
Connective Tissue/Rheumatic Disease  
Dementia  
Diabetes Without End Organ Damage  
Diabetes With End Organ Damage  
Hemiplegia  
Liver Disease Mild to Moderate  
Liver Disease Severe  
Myocardial Infarction  
Peripheral Vascular Disease  
Renal Disease  
Ulcer Disease  
 
Charlson Group Score

 

Step 2. Calculate the risk score, including the Charlson group.
Patient age, Charlson score group, planned procedure type, gender, and the teaching status of the hospital are indicated.  The point values are assigned accordingly to yield an additive score.  By clicking on the "Calculate Estimated Mortality" button, this score is then assigned to the appropriate risk score group, and the mortality for that group is displayed.
